Go back to the website for whatever it is you're using and search FAQs and Application section for 'relay drivers'. You're unlikely to comprehend anything more.

You could probably use a logic-level n-channel mosfet, something like
FDV301.
I'm designing a board that needs about 125 relays. Turns out that
modern nfets don't need flyback clamp diodes, which will save me some
room I need for routing traces.
Ridiculous response for the context.

That's usually a CMOS output from an Arduino (or some such); the
relay, though, what does IT require? There's different answers for
the current to drive different relays.
Appliances (and trucks, and aircraft...) use 24V nominal.
Automobile (12V) relays might be 300 ohm windings, and require
a 12V power source (8 to 20V is probably close enough) which might
(or might not) be grounded to the same '0v' as your logic.
If you want to drive more than one relay, there's ganged drivers
available (integrated circuits, cheap ones).

I think I used one last summer to dig a splinter out of my thumb.

They don't? I guess I'm not using "modern" NFETs then ... :(
Or are you just gonna rely on the body diode?

curiosity, I tested a few that didn't, including a 2N7002 and an
FDV301. Both avalanched nicely at around 20% over rated voltage, which
sounds deliberate to me. Somebody here said that all modern mosfets
have controlled avalanche.

It is the only reasonable response in the whole thread. OP is hobbyist working with a hobbyist part/ project. He is best served by the tutorials on the hobby project site. All those sites can be searched. I told him to search for 'relay drivers'. It's
